I am currently trying to almost completely switch to Ubuntu Linux right now, and for the most part, it is working just fine. Here are just the few things that I don't have completely working yet,
Running an ad-hoc wireless network
Getting WINE to work, because there are still a few Windows only programs I have to run
and not being able to delete the files on my other HDDs which are in the NTSF format
Other then that, Linux is working great.
BTW, if you are reading this, please comment so that I know that people actually read this.
